' Tau whom, it may concern.-

Be it known that 1, JOHN BLALR, asubjeet of the Queen of Great Britain,residing at 1 Brooklyn, in the county of K ings and State of New York,have invented certain new and useful Improvements in Fountain P'ens andI do declare the following to be a full, clear,

it appertains to make and use the same, Tet

erence being had to the accompanying drawtion. .jr .5

. part'of the body in section. gitudi-nal section of the pen enlarged.

' ings, and to the letters of. reference marked thereon, which form apart of this specifica- This invention relates to fountain-pens in whicha supplyof soluble ink material is provided in the pen-body and which isconvertibleinto ink by contact with water.

The invention includes means for storing the ink material in thepen-body and an improved device for conveying the ink solution to thepen-point when the pen is in use.

The accompanying drawings illustrate the invention.

Figure 1 is a side view of the invention with Fig. 2 is a lon- Fig. 3 isa side of feed-bar enlarged. Fig. 4 is a cross-section on the line a: mof Fig. 1, and Fig. 5 is a cross-section on the'line y y of a Fig. 1.

Like letters of reference in the drawings denote corresponding parts inthe several views. y

The letter A indicates the-hollow body of the pen with threaded end toreceive the threadednd.hoflthe pen-section B.

O is the cap, adaptedfto fit'ove'r thegroiht D of the pen and having anextension (1 for insertion in the socket e at the rear end of the body Awhile the pen is in use.

The sectionB has an eccentric opening f lengthwise through it, intowhich is loosely tittedthe straight tubular feed-bar g. This feed-barhas a short slit h at-its rear end and 5 a longer slit at its forwardend, forming at the forward end the fingers i i, the first of which isbroken off about midway of its length and the other, 2", is' adapted tolie along upon the nib D, which rests in the space between the fingers.The finger t" is equally efiective on the concave or theconvex side ofthe nib. The inner part of the front end of the section B iscut away toform a seat j for the pen-nib.

The invention is made operative by adj usting the nib and feed-bar inplace. Then unscrew the section-B and pour into the body A solubleink-powder to the depth of about onehalf inch. Upon this drop alittlewater sufficient to moisten it well. upon it a small wad or plug Zof cotton or other porous material previously moistened with this ink.Now fill the body with water, screw on the section I), remove the cap tothe socket e, and the pen is ready for use. The Water is quickly changedinto ink,which flows through the hole g in the feed-bar g and out uponthe mo,

When the ink fluid is exhausted, refill with water and continue to dothis until the powder is all dissolved, when a new supply is put in, asat first.

IVhat I claim, and desire to secure, is-

A fountain-pen having a layer of soluble ink-powder within the closedend of its hollow body a porous plug fitted against said ink-powder, asupply of water in contact with the plug and means for conveying the inksolution through the pen-section to the nib when the pen is held inoperative position.

In testimony whereof I aflixmy signature inpiesenceof twowitnesses.
